Garage Door Springs in Firestone, CO: Why DIY Replacement Is Dangerous
2026-05-26 7 min read
Here's what most homeowners don't realize about garage door springs in Firestone: they're not just metal coils. They're precision-engineered components under extreme tension, storing enough energy to launch a car. I've seen fingers broken, garage door openers destroyed, and entire doors collapse because someone tried a DIY fix. This isn't fear mongering. It's what happens when springs fail without professional intervention.
Why Garage Door Springs Fail (And It's Sooner Than You Think)
Springs last roughly 7 to 9 years under normal use. That's it. Temperature swings in Colorado, from brutal winter cold to hot summers, accelerate wear faster than most climates. A snapped spring doesn't announce itself gently. Your door will either hang lopsided, refuse to open, or drop suddenly when you hit the opener button.
The two main types are torsion springs (horizontal, above the door) and extension springs (vertical, on each side). Torsion springs are the workhorses on most modern garage doors. Extension springs are older, more prone to sudden failure, and frankly more dangerous when they let go. Either way, replacing them requires specialized tools, exact tension calculations, and years of hands-on training.
I've watched homeowners spend hours on YouTube videos, then call us in panic mode after nearly losing a finger or realizing their door is now misaligned. The cost of a mistake? Far higher than the original estimate.
The Real Cost of Garage Door Spring Replacement
A lot of people ask about cost before they ask about safety. Fair question. A basic torsion spring replacement runs $300 to $500 per spring in the Firestone area, including labor. Extension springs are typically $200 to $400 per spring. If both springs are worn (common), you're looking at $600 to $1,000 total.
That might sound steep until you compare it to fixing a bent door ($800+), replacing a burned-out opener ($400 to $700), or worse, a hospital visit.

When to Call Professionals (Not YouTube)
If your garage door won't open, opens unevenly, or you hear a loud bang from the garage, a spring has likely snapped or is on its way. Don't try to force it up manually. Don't call a handyman. You need someone who works on garage doors every single day.
Professional technicians have proper equipment: winding bars designed to hold tension safely, torque gauges to set spring tension exactly right, and safety cables that catch a broken spring before it becomes a projectile. We also inspect the rest of your system (opener, tracks, hinges, rollers) while we're in there, because a broken spring often signals that other parts are wearing too.
If your garage door is over 10 years old, both springs are likely approaching the end of their life simultaneously. That's why we often recommend replacing both at once, even if only one has failed. It prevents a second emergency call in six months.
DIY Risks That Aren't Worth It
I want to be direct: replacing garage door springs yourself can cause serious injury or death. Springs are under 200+ pounds of tension per side. If a winding bar slips, it can crush your hand. If a spring unwinds unexpectedly, it can snap across your face or chest. Emergency rooms in the Denver metro area see preventable garage door injuries every month.
Beyond personal safety, an improperly tensioned spring will wear your opener faster, misalign your door, and create new problems you didn't have before. A professional install comes with confidence that the job is done right. We also handle all disposal of old springs properly (they're not trash, they're scrap metal).

What to Expect During Professional Replacement
When you call Garage Door Company Firestone for a spring replacement, here's what happens. First, we schedule a same-day visit if possible (we often can). A technician arrives with tools, springs, and a safety-first mindset. We'll inspect both springs, measure the door, and confirm the spring type and size.
Next, we disable the opener, safely unwind the old spring(s), and install new ones with precise tension. We test the door multiple times to ensure smooth, balanced operation. The whole job usually takes 1 to 2 hours. We clean up, explain what we did, and give you a warranty on parts and labor.
If your door needs other repairs (track alignment, roller replacement), we'll flag that during the estimate. No surprise charges.
Act Now Before Spring Failure Becomes an Emergency
A snapped spring doesn't wait for convenient timing. It fails at night, in bad weather, or when you're rushing out the door.

Frequently Asked Questions
How long do garage door springs last? Most springs last 7 to 9 years with regular use. Colorado's temperature extremes can shorten that lifespan. Proper maintenance, like lubrication and opener balance checks, helps springs reach their full life expectancy.
Can I replace just one spring if the other is still working? Technically yes, but we usually recommend replacing both. Springs age together, and the second one will likely fail within months. Replacing both at once saves cost, prevents repeat service calls, and ensures balanced door operation.
What's the difference between torsion and extension springs? Torsion springs mount horizontally above the door and twist to lift it. Extension springs run vertically on each side and stretch. Torsion springs are safer, last longer, and are standard on modern doors. Extension springs are older, more prone to sudden failure, and more dangerous.
Why is spring replacement so expensive? You're paying for specialized knowledge, safety equipment, and liability insurance. A mistake costs thousands in repairs or medical bills. Professional installation also includes testing, adjustment, and warranty protection.
Do you offer emergency spring replacement in Firestone? Yes. Call 720-706-2893 anytime. We prioritize emergency calls and often dispatch same-day for snapped springs. Our emergency service page has more details on availability and response times.
